Re: Thermal Load Calcs (summary)

  • From: Greg Skafte

For peoples future reference  for devices where you can't find Heat Dissapation
/Thermal Load etc.  I've finally found a couple of numbers that you can use

 	1 Watt = 3.5->3.7  B.T.U/Hour 

the refernces varied.  Size of Room is irrelavent for the thermal load, it is
only relevent when sizing the fan in the chiller.  As an additional note 
most chillers are sold in tons ie 1ton,2 ton,65 ton.  A ton is defined as
12,000 B.T.U/Hour of cooling capacity.  

Most sites have Thermal loads only for the "big" gear not the little stuff so
thanks to the people who forwarded the URLS that lead me in the right direction.

When things can't get any worse, they simplify themselves by getting a whole
lot worse then complicated. A complete and utter disaster is the simplest
thing in the world; it's preventing one that's complex.       (Janet Morris)
